Dianthus plant named ‘KLEDP22351’

ABSTRACT

A new  Dianthus  plant designated ‘KLEDP22351’ particularly distinguished by double light pink flowers having pink centers, a compact growth habit, and an upright plant habit, is disclosed.

Genus and species: Dianthus caryophyllus.

Variety denominations: ‘KLEDP22351’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Dianthus, botanically known as Dianthus cultivars, and hereinafter referred to by the variety name ‘KLEDP22351’. ‘KLEDP22351’ originated from a naturally-occurring, whole plant mutation from the Dianthus parent ‘KLEDP07089’ (Unpatented) in April 2016 in The Netherlands.

In August 2016, ‘KLEDP22351’ was first vegetatively propagated by vegetative stem cuttings in Stuttgart, Germany. ‘KLEDP22351’ was found to reproduce true to type in successive generations of asexual propagation in Latina, Italy and Stuttgart, Germany via vegetative cuttings.

SUMMARY

The following are the most outstanding and distinguishing characteristics of ‘KLEDP22351’ when grown under normal horticultural practices in Stuttgart, Germany.

-   -   1. Double light pink flowers having pink centers;     -   2. A compact growth habit; and     -   3. An upright plant habit.

DESCRIPTION OF THE PHOTOGRAPH

This new Dianthus plant is illustrated by the accompanying photograph of a 14-week-old plant taken in May 2017 and grown in a greenhouse in Stuttgart, Germany. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is a whole plant photo of ‘KLEDP22351’ and shows the foliage, buds, and flowers.

DESCRIPTION

The following detailed descriptions set forth the distinctive characteristics of ‘KLEDP22351’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. Data was collected in November 2021 on plants 23 weeks after potting and grown in a plastic greenhouse. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 5^(th) edition (2007).
